Hi Damjan,
I have tested the patch using ConnectX-4 EN (2x50G) with MLNOX_OFED 4.1.x on
Xenial 16.04.2 (Kernel generic 4.11.12) with stable/17.07 branch
Reason for kernel 4.11 was Mellanox requested 4.8 or later and other
requirements pointed to 4.11, hence collapsing to the newer one.
Status:
a) With the patch I now stopped seeing the "UnknownInterface" but 50GE
interface is seen as 100GE even when cabling a QSPF and kernel sees 40G speed.
localadmin@sm981:~$ sudo ethtool ens1f0

b) I get the following error message at VPP start

Hi,
I have ConnectX-4 50GE interfaces running on VPP and for some reason, they
appear as “Unknown” even when running as 40GE.
